Turning a percent grade into a degree necessitates the conversion of a slope expressed as a percentage into an angular measure. This process involves the application of trigonometry, particularly the tangent function. The conversion formula is represented as Degree = Arctan(Percent/100), where 'Degree' signifies the angle and 'Percent' symbolizes the slope in percentage terms.
